SNARE proteins are found in Golgi bodies as well as Endoplasmic reticulum.
A soluble N-ethylmaleimide-sensitive factor activating protein receptors is SNARE.
SNAREs are short proteins that are bound to the surface of the vesicle and the membrane, connected by a segment that crosses the membrane or by covalently-attached lipid chains.
When the SNARE proteins come together, they form a tight bundle of alpha helices that pull the membranes into proximity.

The coding strand of DNA has the polarity 5' - 3'.
DNA is double-stranded, but only one strand serves as a template for transcription at any given time. The coding strand is the strand used when displaying a DNA sequence. It is presented in the 5' to 3' direction.
This template strand is called the noncoding strand. The non-template strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule.

An example of a heterozygous but homogeneous population is the Hybrid variety.
A hybrid variety has homogeneous but heterozygous population.
Synthetic and composite varieties are developed in cross-pollinated species. Such varieties consist of several homozygotes and heterozygotes and thus constitute a heterogeneous population.

The light phase of photosynthesis is not affected by Temperature.
The light-dependent reactions of photosynthesis are not affected by changes in temperature, the light-independent reactions of photosynthesis are dependent on temperature. They are reactions catalyzed by enzymes.

The endosperm provides nutrients to the embryo as it contains Hormones, Vitamins and Enzymes.
The endosperm is a tissue produced inside the seeds of most flowering plants following double fertilization.
It is triploid in most species, which may be auxin-driven. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.

Incomplete dominance was first observed in the 4' O clock (Mirabilis jalapa) plant. This was first observed by Carl Correns.
Incomplete dominance results from a cross in which each parental contribution is genetically unique and gives rise to progeny whose phenotype is intermediate. Incomplete dominance is also referred to as semi-dominance and partial dominance.

Heterosis is most often exploited in Cross pollinated species.
cross-pollinated (hybrid) plants have “greater height, weight, and fertility” than their self-pollinated counterparts. The observation that cross-pollinated hybrids is more vigorous than their parents is nowadays commonly referred to as heterosis.
Heterosis describes the phenomenon in which hybrids formed between individuals of the same or closely related species are more robust or vigorous than their parents.
Thus, cross-pollinated species are often exploited.

The embryosac of angiosperm contains Eight nuclei.
Embryo sac is the gametophyte of angiosperms and it contains typically eight nuclei; that are two synergid cells, an egg cell, three antipodal cells, and two polar nuclei.
The cytoplasm associated more or less directly with these nuclei is not partitioned by cell walls.

a. Alternative form of a gene that cannot go together in the same gamete is an allele.
b. A phenotype caused by the environment which resembles a phenotype caused by a gene is Phenocopy.
c. Crossing of F₁ with a homozygous recessive parent is a Test cross.
d. Gene which has a masking effect on another gene is the Epistic gene.

Wheat crop is a self-pollinated crops.
The transfer of pollen from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower is termed self-pollination. And plants that undergo this sort of pollination are termed self-pollinating crops.
e.g: beans, broccoli, cabbage, carrots, cauliflower, corn and onions.
wheat produces seed when pollen from anthers fertilizes the receptive ovary in the same flower of a single-parent plant.
